My husband does not like boiled foods too. He preferes fryed ones. So it is practically impossible to convince him to eat something boiled. But... when he sees me eating somethiung "special" he wants to taste what I eat. ;-) Imagine, he eats all my boiled vegetables now.
It is not difficult to cook string beans. "Difficult" is to clean them. Because if you bought them fresh, you have to eliminate all their "tails". From both sides. And you have to remain only their "body".

After that you have to put them in boiling salted water (not to much!) and boil them about 15 minutes. Put them in a plate, add olive oil (I use olive+sesame oil, they say sesame oil is very good for health too) and vinegar (balsamic vinegar from Modena). You can see them on the lunch photo here too: Simple Rules Of Healthy Meals And Weight Loss
